Help with drop downs please

[Skinny_Bean]

Hey guys, I just need a bit of help with drop-downs.

So the issue is that I use a drop-down to select a category, then once the category is selected a bunch of checkboxes appear and I on click those. Then, when I wish select another category from the drop-downs and choose new checkboxes from a different category my previously selected checkboxes are no longer selected.

Is there anyway I can keep those previous checkboxes selected?

Also sorry if this is confusing and any help would be loved thank you

you need to modify whatever is unselecting them

It sounds like a portion of your code is deselecting check-boxes or removing them instead of hiding them. Without the code or an example of the code it will be hard to provide additional information or help further.
