Milestone Patterns Share Share via LinkedIn Reddit Email Copy Link Print On This Page Tip: Interface patterns give you an opportunity to explore different interface designs. Be sure to check out How to Adapt a Pattern for Your Application. Goal There are three options for milestone patterns which all display some form of a progress indicator to guide users through a series of steps. This page explains how you can use this pattern in your interface, and walks through the design structure in detail. In each of the patterns, the indicators change color to show that the user has completed those steps in the task. These patterns can be used to break up longer forms into more manageable sections and combine smaller forms into a more streamlined process. All five patterns have similar functionality and design, but provide different levels of detail and context for the steps. They all are located under the PATTERNS tab under PALETTE in your interface. Test out all three to see which option works best for you. Milestone (Bar) The main interface components in this pattern are columns layout, card layout, side by side layout, dynamic link, rich text item, and rich text icon components. This pattern also relies on a few functions to create the interactive milestones; including a!forEach() function, if(), and choose() functions. You can examine the entire expression or jump down to the subsections below with referenced line numbers to see a detailed breakdown of the main components and functions. Pattern expression The milestone bar pattern introduces a 254-line expression to the interface. [Line 1-5] Set local variables At the beginning of the expression, two local variables are set up: local!milestoneBarSteps, which provides the titles for the four steps in the milestone and local!currentMilestoneBarStep, which stores the current step that the user is on. This pattern has the user starting on the second step in the milestone bar. This is done to show that the user can return to a previous step using the Back button. 1 2 3 4 5 { a!localVariables( /* List of steps in the milestone bar */ local!milestoneBarSteps: {"Review Cart", "Provide Shipping", "Provide Billing", "Confirm Order"}, local!currentMilestoneBarStep: 2, [Line 6-166] Define milestone steps This section creates each step in the milestone bar using a!forEach(), if(), rich text items and rich text icons, and a dynamic link. Each step in the milestone bar is constructed with a column layout that contains a card with the title and icon for the step within a side by side layout. The expression that constructs each step is iterated through using a!forEach() [lines 9-162]. The style of the card layout, the boldness of the text, and the icon change as you move through the steps: Current step [lines 111-159]: the text is bold or "STRONG", the card style is "ACCENT", and the icon is a pointing hand. Previous steps [lines 12-64]: the text is normal, the card style is "ACCENT", and the icon is a check mark. Future steps [lines 66-110]: the text is normal, the card style is light gray, and there is a number in place of an icon. Two nested if() functions are used in conjunction with local!currentMilestoneBarStep to determine whether each step is a previous, future, or current step and display the behavior accordingly. This is done by using a dynamic link within the card layout of the Current step to save the step's number into local!currentMilestoneBarStep. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 { a!columnsLayout( columns: { a!forEach( items: local!milestoneBarSteps, expression: if( /* Completed step */ fv!index < local!currentMilestoneBarStep, a!columnLayout( contents: { a!cardLayout( contents: { a!sideBySideLayout( items: { a!sideBySideItem( item: a!richTextDisplayField( labelPosition: "COLLAPSED", value: { a!richTextItem( text: { a!richTextIcon( icon: "check", altText: "Completed step" ) }, size: "MEDIUM", style: "STRONG" ) }, align: "CENTER" ), width: "MINIMIZE" ), a!sideBySideItem( item: a!richTextDisplayField( labelPosition: "COLLAPSED", value: { a!richTextItem( text: upper(fv!item), size: "MEDIUM" ) }, align: "LEFT" ) ) } ) }, /* Link to go to selected step */ link: a!dynamicLink( value: fv!index, saveInto: local!currentMilestoneBarStep ), style: "ACCENT", showBorder: false, accessibilityText: "Completed step.

The choose function works with local!currentMilestoneBarStep to determine which step's message to show. Currently there is a placeholder message in the rich text display components, however you can replace this with the component that you want to display for each milestone. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 choose( local!currentMilestoneBarStep, { /* Replace this rich text with the component or rule that should populate this step */ a!richTextDisplayField( labelPosition: "COLLAPSED", value: {a!richTextItem(text: "The contents of the first step belong here", style: "EMPHASIS")}, align: "CENTER" ) }, { /* Replace this rich text with the component or rule that should populate this step */ a!richTextDisplayField( labelPosition: "COLLAPSED", value: {a!richTextItem(text: "The contents of the second step belong here", style: "EMPHASIS")}, align: "CENTER" ) }, { /* Replace this rich text with the component or rule that should populate this step */ a!richTextDisplayField( labelPosition: "COLLAPSED", value: {a!richTextItem(text: "The contents of the third step belong here", style: "EMPHASIS")}, align: "CENTER" ) }, { /* Replace this rich text with the component or rule that should populate this step */ a!richTextDisplayField( labelPosition: "COLLAPSED", value: {a!richTextItem(text: "The contents of the fourth step belong here", style: "EMPHASIS")}, align: "CENTER" ) } ), [Line 202-254] Define navigation buttons The last section contains columns with buttons that allow users to go back to the previous step, to cancel their progress, or move to the next step. Once the user has made it to the final milestone, the label on the Next button changes to Submit and acts as a submit button. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 a!columnsLayout( columns: { a!columnLayout( contents: { a!buttonArrayLayout( buttons: { a!buttonWidget( label: "Back", value: local!currentMilestoneBarStep - 1, saveInto: local!currentMilestoneBarStep, style: "NORMAL", showWhen: local!currentMilestoneBarStep > 1 ), a!buttonWidget( label: "Cancel", style: if( local!currentMilestoneBarStep = 1, "OUTLINE", "LINK" ) ) }, align: "START" ) } ), a!columnLayout( contents: { a!buttonArrayLayout( buttons: a!buttonWidget( label: if( local!currentMilestoneBarStep = length(local!milestoneBarSteps), "Submit", "Next" ), saveInto: if( local!currentMilestoneBarStep = length(local!milestoneBarSteps), {}, a!save( local!currentMilestoneBarStep, local!currentMilestoneBarStep + 1 ) ), style: "SOLID" ) ) } ) } ) } ) } Additional milestone patterns In addition to the Milestone (Bar) pattern described above, the Milestone (Stamp), and Navigation (Vertical) patterns are also available in your interface. They're located in PALETTE, under the PATTERNS tab. Milestone (Stamp) The Milestone (Stamp) pattern displays a simple progress indicator to guide users through steps in a task. The main components of this pattern are stamps, rich text display components, and side by side layouts. They're configured to display the progress of a given task. The image below shows the pattern with callouts for the main components. Pattern expression When you drag and drop the Milestone (Stamp) pattern onto your interface, 117 lines of expression will be added to the section where you dragged it. Milestone (Vertical) The Milestone (Vertical) pattern displays a detailed progress indicator to guide users through steps in a task. The main components of this pattern are stamps, rich text display components, and column layouts. They're configured to display the progress of a given task. The image below shows the pattern with callouts for the main components. Main components: Stamp with icon and "POSITIVE" background color showing a completed step. Rich text showing the bolded name of the step and the date completed. Stamp with icon and grey background color showing a future step. Rich text showing the name of the step. Pattern expression When you drag and drop the Milestone (Vertical) pattern onto your interface, 121 lines of expression will be added to the section where you dragged it. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 { a!localVariables( local!verticalSteps: { a!map(name: "Claim Filed", icon: "archive", date: today() - 5, isCompleted: true), a!map(name: "Vehicle Inspected", icon: "search", date: today() - 4, isCompleted: true), a!map(name: "Estimate Issued", icon: "file-text-o", date: null, isCompleted: false), a!map(name: "Payment Sent", icon: "money", date: null, isCompleted: false), a!map(name: "Claim Closed", icon: "stamp", date: null, isCompleted: false) }, a!sectionLayout( label: "Claim Progress", labelSize: "MEDIUM", labelColor: "STANDARD", contents: { a!forEach( items: local!verticalSteps, expression: { a!columnsLayout( columns: { a!columnLayout( contents: { if( fv!item.isCompleted, a!stampField( labelPosition: "COLLAPSED", icon: "check", backgroundColor: "POSITIVE", contentColor: "STANDARD", size: "TINY", align: "CENTER", marginBelow: "NONE", accessibilityText: "Completed Step" ), a!stampField( labelPosition: "COLLAPSED", icon: fv!item.icon, backgroundColor: "#d9d9d9", contentColor: "#666666", size: "TINY", align: "CENTER", marginBelow: "NONE", accessibilityText: "Future Step" ) ) }, width: "EXTRA_NARROW" ), a!columnLayout( contents: { a!richTextDisplayField( labelPosition: "COLLAPSED", value: { a!richTextItem( text: fv!item.name, size: "STANDARD", style: if( fv!item.isCompleted, "STRONG", "PLAIN" ) ) }, preventWrapping: true, marginBelow: "NONE" ), a!richTextDisplayField( labelPosition: "COLLAPSED", value: { a!richTextItem( text: text(fv!item.date, "MMMM D"), size: "SMALL" ) }, preventWrapping: true, showWhen: fv!item.isCompleted, marginBelow: "NONE" ) } ) }, alignVertical: "MIDDLE", marginAbove: if( fv!isFirst, "STANDARD", "NONE" ), marginBelow: "NONE", spacing: "NONE", stackWhen: "NEVER" ), a!columnsLayout( columns: { a!columnLayout( contents: { a!imageField( labelPosition: "COLLAPSED", images: { a!documentImage( document: a!EXAMPLE_VERTICAL_CONNECTOR_IMAGE() ) }, size: "TINY", align: "CENTER" ) }, width: "EXTRA_NARROW" ), a!columnLayout() }, alignVertical: "MIDDLE", showWhen: not(fv!isLast), marginBelow: "NONE", spacing: "NONE", stackWhen: "NEVER" ) } ) } ) ) } Feedback Was this page helpful?
