Global way to force auto-expand dropdowns in Frameless

[WoutJacobs]

version - RH 2022.3.93

Output preset - Frameless

---

For some reason, a few writers want the dropdowns to auto-expand upon loading the page.

I can achieve this for an individual dropdown with the attribute data-expanded="true".

***

Before I loop through all dropdowns in my project, I'd like to ask if I'm not overcomplicating things and if there is a simpler way of doing this?

I don't recall any control in the Preset for being able to do this [set them all to auto-expand], so your approach is probably fine.

It's not what you want but the icon below allows your users to expand/contract all.

In Author mode when editing, click within one dropdown and the context menu has expand/contract all options.

If you can find the code that makes that button work in the skin you're using, you should be able to bung it in a script so you don't have to write your own code.

For example, I tried this in the master page of a RH2019 Frameless project. You can probably also add it in the User Assets section of the skin as an attached JS file. Note I'm just a hack and can't advise on best practices. 

Note: you'll need to check the code for RH2022 as I'm sure it's changed in newer versions.

Also test thoroughly as I couldn't say what side effects might result. Probably consult a friendly developer if you have one. 🙂

  document.addEventListener("DOMContentLoaded", (event) => {
    rh.model.publish(rh.consts('EVT_EXPAND_COLLAPSE_ALL'));
  });

(The first and third lines make sure the html has all been loaded before the script runs - I think it's necessary but you could try without them if you want. The second line is the button code I found in my skin under Topic Page Buttons > Expand/Collapse All > OnClick)

I'm also assuming you want this in your output, rather than in the RH editor. I think Peter's manual suggestion would be the only option in the editor.
