[2.0.0-rc2] Configuring a slot on Layout Builder make the page to redirect on the block form

Please note, it seems it is not happening with theme ui_suite_dsfr for example.

just a question, i am not sure about it : would it be related to how dropdown buttons are managed in bootstrap?

Yes, because in fact, no matter which block is used in Layout builder, as soon as we have a slot (for example in a component block in LB), and the dropdown button to add a source, it does not work anymore.
If i desactiveate the dropdown button, and repace it to a list of buttons, then ajax works again.

so the problem you encountered is clearly related to how dropdown are handled here in ui_suite_bootstrap.
Maybe we are not constructing well the dropdown ? i don't have the final answer yet

would you have some feedbacks about dropdowns please :) ?

@grimreaper, would you try something for me ?

in the src/Element/ComponentSlotForm.php, in function buildComponentDropbutton (around line 400),
add a first line return $elements;.

Then it seems everythings works, could you confirm please?

OK for me because:

• The new UI is good enough for me
• It is the same data structure

Christian, if you are OK too, we merge:

                component_id: null
                variant_id:
                  source_id: select
                  source:
                    value: ''

Decided collectively during the weekly.

Instead of a list of buttons inside a fieldset, let's try with a select form element with:

• - Select a source to add - as empty option of the form element
• An AJAX mechanism (using the Druapl Form State API) to submit on change
