Not sure about the not showing, since you seem to already have swapped it for a native bricks form.
As for localization…
Scroll all the way down here → Form Element – Bricks Academy till u reach " Localize the date picker strings". Then just paste the code as instructed in the article, put in your form id and switch the XX for your locale which I guess is nl. You can find all available locales here → https://github.com/flatpickr/flatpickr/tree/master/src/l10n
I understand the problem. The FlatPickr library is currently loaded only when it detects that there are forms with date field on the page. Since you are using Bricksforge popups and they are reloading the content via Ajax, Flatpickr is missing here. I’ll see how I can solve the problem. As a workaround, you could use native Bricks popups here. The native ones are not loaded via Ajax and are in the background of the page. So Flatpickr will load properly here.
That’s a pity that I need to chose between a bf popup and a pro-form with date picker. I liked how BF popup smoothly appears and dissapears. I can’t make it with genuine bricks. Well, I have to choose this time. But I hope in future projects I won’t need to choose if I happen to have the same combination )).
The Bricks native form has the same behavior on popups. Just prevent the body to scroll while the popup is open deactiating the "Scroll (body) control:
The reason why Scroll Body disabling didn’t work for me and the page still scrolled when popup is visible is the BF Smooth Scroller… One more feature that I have to disable
Change to Lenis Scroll Smoother. That’s a GSAP limitation. We can’t do nothing to fix that. GSAP is changing the scroll context. Lenis will work much better here. You can change the provider via the settings icon on „Scroll Smoother“.
Nope, it was set to lenis initially. When i got the reply on bricks forum, i tried to switch to gsap. But the page stoped scrolling at all(scroll bar moved, but the page content didn’t ) . So i switched back to lenis. This behaviour is when lenis is set… Now i disabled the smooth scroller and the page does not scroll when popup is visible.
