Conditional field showing using arcade in map viewer popups

SRanseen — Wed, 01 Jun 2022 16:52:47 GMT

Hi all

I am new to arcade and have mostly only used it in field map forms and labels.

I need to hide a field in the pop up based on the attributes of a separate field.

The project is our adopt a street program. The user wants the link to adopt a street hidden if the street is already adopted or pending adoption. They also want the adopted group name field to be hidden if the street is available. I saw methods to hide a field based on conditions related to the same field but I did not find a method to hide a separate field based on another fields attributes.

Link to web app we are using the web app to embed the map in the adopt a street website.

What I am looking for:

If ($feature, "street_adoption_status") != "Available" than $feature["Link_Txt"] is not visible in pop up

If ($feature, "street_adoption_status") == "Adopted" than $feature["group_name"] is visible in pop-up

Any help is appreciated. Thank you for your time.

This isn't possible in the default fields element.

There's (at least) 2 options:

write custom HTML in a text element (switch to HTML source) or an Arcade element, using the display style attribute to control whether you want to show a value or not:

<table> <tr><td>Street</td><td>{street_map}</td></tr> <tr style="display:{expression/expr0};"><td>Group></td><td>{group_name}</td></tr> </table>

// expr0 // style="display: block;" shows the element // style="display: none;" hides the element if($feature.street_adoption_status == "Adopted") { return "block" } return "none"

define your fields in an Arcade element:

var trash_val = `${$feature.Total_Trasj} lb` if(trash_val == " lb") { trash_val = null } var field_values = { "Street": $feature.street_map, "Street Adoption Status": $feature.street_adoption_status, "Street Length": `${Round($feature.Miles, 2)} miles`, "Total Trash": trash_val, "Adopt-A-Street Application": $feature.Link_Txt, "Adoption Group": $feature.group_name } var fields = [ {"fieldName": "Street"}, {"fieldName": "Street Adoption Status"}, {"fieldName": "Street Length"}, {"fieldName": "Total Trash"}, ] if($feature.street_adoption_status == "Available") { Push(fields, {"fieldName": "Adopt-A-Street Application"}) } if($feature.street_adoption_status == "Adopted") { Push(fields, {"fieldName": "Adoption Group"}) } return { type: 'fields', "fieldInfos": fields, "attributes" : field_values }

Thank you. I would not have figured that out with my current Arcade coding knowledge.

Hi Johannes,

The HTML opposite (First) to hide the fields from showing in the pop-up is this HTML code for the latest Map Viewer or for Map Viewer classic (or both?)

Thanks!

I know it works with Map Viewer Classic, but it should also work with the new Map Viewer.
