Hi there, thank you for the extension, it is really promising. Sadly, I had to deinstall it for one of my clients, as one of the editors experienced severe problems (they would always find all of the items closed again, no status remembering for them). For the others, it worked fine, but as this is the power user, we had to reconsider.
I would like to ask for two configuration options per user, which would mitigate such problems and cater for personal preference.

1. allow a user to deactivate the extension in their user settings. No trace will remain, or the collapse button will just be there but inactive, all items are open - like the ext was never there.
2. allow initially all items to be open, not closed as in the current version. Editors can then choose whether to collapse all items (in their user settings) and use the ext as is now, or choose to have them all open and only collapse what is necessary.

Thank your for consideration and all the great extensions you provide.

Collapsing some elements on a page and later revisiting the same page with the same user displays all elements in the expanded state. According to readme, I would expect the state of collapsed elements to be restored, same as #1.

I can confirm this behavior for TYPO3 11.5.30 and Collapse 1.0.0, the collapse state was not saved when I revisited the page.

After some troubleshooting, it looks like the field is not created in the user settings. You either do an addToList or removeFromList in PageModuleCollapse.js, but the field b13.collapse is never set.

I missed something like that in your PageModuleCollapse.js:

if (PersistentStorage.isset('B13.Collapse') === false) {
     PersistentStorage.set('B13.Collapse','');
}

On the first call, the field is created so that I can add or remove a value. This works for me.

Hi there,

are there plans for a v12 support?
Would go deeper into that extension if there is no short-term plan or existing work which can be released soon.

I installed the extension and noticed that all content elements are now collapsed automatically by default (not sure if that is the intended behaviour). The to-top arrow is shown in the button.

when I click on the icon to expand the preview, the preview opens but the icon doesn't change:

it changes only after I click another time.

Collapsing some elements on a page and later revisiting the same page with the same user displays all elements in the expanded state. According to readme, I would expect the state of collapsed elements to be restored.

Update: Problem might be due to using outdated browser. So, better alternative might be updating browser. See compat. matrix: https://developer.mozilla.org/en-US/docs/Web/API/Element/ariaExpanded#browser_compatibility

It has been reported at least twice since extension was activated. At first I could not reproduce it, but after switching browser from Chromium to Firefox, I could.

It was reported that all elements were collapsed. It was possible to expand individual elements, but after reloading the page, the behaviour was the same (all elements collapsed).

Overrall, we saw 2 different problems:

1. when element was collapsed, this was not saved. Looks similar to #1 and #7 and seemed to be fixed with #10
2. (this issue) all elements collapsed, not possible to change behaviour. Depends on Browser

I will create PR.

Possible solution

changing

- if (btn.ariaExpanded == 'true') {
+ if (btn.getAttribute('aria-expanded') == 'true') {

in PageModuleCollapse.js

was reported to work.

Info

Behaviour may be browser-dependant, see also

Versions

• TYPO3: 11.5.38
• container: 2.3.6
• collapse: latest 1.0.0 (or latest "main")

reproduced with

• Firefox 115.12.0esr (64-bit) "Extended Support Release", Xubuntu (Linux)

Note: I usually do not use Firefox, this might be an outdated version. The other colleagues are usually under Windows using automatically updated versions.
