Hide form fields on entity form on portal

[aberson]

Hello,

I have an entity with lookup fields to customer and contact. I have the contact lookup filtered based on the customer. However if someone chooses contact first they can select any contact.

Is there a way to disable or hide the contact field till a customer is selected?

The end goal is to make sure the contact is associated with the customer selected at form submit.

I have tried business rules but they don’t seem to work on portals..

@aberson - Form fields are available to you in JavaScript to extend or modify the behavior such as show / hide or enable / disable. See documentation  here provided for web forms but should work for entity forms as well.

Business rules do not work with portal forms.

Hi @aberson ,

Could you please share a bit more about your scenario?

Do you want to disable or hide the Contact field till the Customer field value is selected?

Based on the needs that you mentioned, I think the "Business rules" functionality in CDS Entity could achieve your needs. I have made a test on my side, please consider take a try with the following workaround:

More details about creating a Business Rule for a Entity, please check the following article:

Please consider take a try with above solution, check if the issue is solved.

Best regards,

Thank you for the response. Either hiding or disabling can work.

I don’t think the business rules work when the CDS form is displayed on a portal.

I tried the java and am unable to select the entire input. I can hide the input by using .parent() and the label separately.

However, if i start with the field hidden from the form i can't grab it to show it.... I can't seem to find the logical name of the entity form input to take action on it....

Hi @aberson ,

Have you taken a Custom JavaScript to achieve your needs?

Based on the needs that you mentioned, I also agree with @sandeepd 's thought almost. You could consider add a custom JavaScript to the Entity form to control the form field visible or invisible through Power Portal Management.

I have made a test on my side, please consider take a try with the following workaround:

Please consider go to your Portal Management (Model-Driven app), then click "Entity forms" tab, then select the Entity form where you want to achieve your logic.

Then switch to "Additional Settings" tab, scroll down to the "Custom JavaScript" part, type the above JavaScript code, then save your Entity form.

$(document).ready(function(){
    var currentValue =  $("#crba2_customer").val();
    if(currentValue==null || currentValue == ''){
        $("#crba2_normalcontact").style.display = 'none'
    }else{
        $("#crba2_normalcontact").style.display = 'block'
    }
})

After that, re-open your Portal, then check if the issue is solved.
