i have a form inside a collapsible panel. the default state is closed. when you click on the tab the panel drops down and the you can enter data into the form. but when you click the submit button the page reloads and the panel reverts back to the closed state so you can't see the results. you have to open the panel again to see the results of the form submission.
how do i make the panel state remain open after clicking the form submit button?
