You can create a field that only displays when certain criteria are met.
Log in to CRM as an Admin user.
In the top right, click the User icon, and select Admin.
Under **Developer Tools**, click **Studio**.
Click the module to add this to.
Click **Fields**.
Click the field you want to make dependent.
Next to the **Dependent** field, select the checkbox.
The formula option will always be present, however if this is a dropdown field you will also have the option to choose a dependent type of Parent Dropdown. For a formula:
Select Edit Formula.
Write the formula that meets your required criteria. Hovering over the available formulas will give their syntax.
If you are creating a dropdown field and wish to use a Parent Dropdown dependent type:
Ensure the dropdown list for the main field contains all options. (For this example, we use the numbers 1-10.)
Under **Parent Dropdown**, choose the decisive dropdown. (For this example, we use a Numbers dropdown with the options Odd and Even.)
Click Edit Visibility.
Here you will drag and drop each number under Odd and Even respectively.
Click Save.
