In our portal we are using Dynamic Container to have the multi tab functionality. Our requirement is that whenever user wants to close any tab , they should be given some custom messages in modal window. For this requirement , we want to disable the dynamic Container's "Close this Tab" option(as shown below) and will only allow user to close the tab from a custom button. as this is an OOTB feature , how this can be disabled? If at all this can be done , can we also add a condition which if returns true will make this option disabled?
