FAQ (Frequently Asked Questions)

What is enable and disable button in LWC?

you can do it by just using the attribute 'disabled' with the value false in the button tag.

How do you make a lightning-input-field mandatory?

To make an input field required on the client only, set required attribute to true in lightning:inputField . Use this attribute if you want to require a value in a field before the form can be submitted, and the field isn't marked required in Setup.

How do you use disabled Lightning buttons?

If you want a button to be disabled by default, the best way to do this is via component attributes using markup. In many cases you'll want to disable the button after it is clicked. You can do that using the event argument passed to controllers.
