Conditional Visibility allows you to specify when you want a particular page component to be visible. We can use this to customise our pages to make information appear when it is relevant to the business process, and be hidden when not, so that we can keep the page as simple and concise for our users as possible.

How to make field non-editable in Salesforce? Go to the page layout. Click the Field Properties in the page layout. Make it Read-Only.

How to make Custom Fields visible: Log in to your Salesforce account. Go to Setup. Select Permission sets. Go to Aircall_PermissionSet. Click on Manage Assignments and then Add Assignments. Select the Users you want to give access to the custom fields below:

Setup ---> Customize ---> Objects ---> Page Layouts ---> Edit the page layout ---> Select the field you want to make read-only ---> Click on 'Properties' of the field(an icon to the right end of field) ---> Here you will get a checkbox to make the field read only.

The only way to do this is with VisualForce. You will have to have code in your controller that determines if the field is an outputfield (read only) or an inputfield (read / write). Then you'll need to call a reRender on the fields on change the dropdown. This blog post may give you some help for this.

Conditional fields allow you to manage sets of dependencies between fields. Such fields are available for editing and display only if the right condition is met. To create conditional fields, you must first create custom fields and then leverage such fields in forms.
