Make custom form button invisible after clicking

[Tashfique]

Hi I have made a custom button thru UI actions. Clicking on it will assign the case to the logged in user and also change the state. 
I need the button to disappear for that task after its clicked. How can I implement that?

The button is Assign to me

Hi,

You can use the condition field in the ui action to show it only when on the specific state and when the logged in user is different from the assigned to.
