Javascript to display default label on choice field

Posted on by Mikello-6626

I am using a model driven app form on the Portal. Is there a way to display a default "--Select--" label on a dropdown field when the form first loads, without creating an actual choice called "--Select--" and assigning that as default. Looking to avoid the problem if user does not select anything, then the default value assigned should be blank and not --Select--

Hi @Mikello-6626

To configure this you can use Entity Form Metadata on the form of type attribute and then provide the default value that you are looking for.

Hope this Helps!

Hi, you can apply JS to achieve that, something like:

$("#<choice field name>").find("option[value='']").attr("label", "--SELECT--")

Thank you so much for your prompt response as always. I am very close to this but for some reason my Power flow is failing because it detects as no value. Any way to assign a value like "Not selected" behind the scenes if a user keeps it as default "--Select--"? I tried assigning value in this code but it's not working
$("#<choice field name>").find("option[value='None selected']").attr("label", "--SELECT--")

So, your flow expects that field to contain a value, is that it?

if yes, then the choice field should be mandatory.. this way the user can't select the option "--SELECT--".. because that option contains no value

You can apply this change on a dataverse level (change column properties to required).. this will make the column always required, both in Portals and Model-Driven App

Or if you want it to be only mandatory in the Portals.. you can apply Form Metadata and set it required: https://docs.microsoft.com/en-us/powerapps/maker/portals/configure/configure-web-form-metadata
