DisclosurePanel how to don't hide the entire panel?

[melokki]

Hello
I have a question regarding the Disclosure component
I want to to be able to press a button and to extend the DisclosurePanel, when I press the button again the DisclosurePanel to become a smaller div element

for example:
I have a grid with 3 columns, when the DisclosurePanel is open I want it to be 2 of the 3 columns of the grid, when I close it I want it to be 1 column from the 3 of the grid

Would that be possible with Disclosure?

What else can you suggest me to get this result?

Never mind, managed to make this much more easy with just some bindings :)
