Sorry my late answers, I'm so focused on my own changes that I forgot to answer 😅

I've checked your code but I will maybe use a different approach, I'll see (I've made a lot of changes to the sliders for the new slider sub-buttons).

Hi again! I wanted to take a look at this but I realize that I don't clearly understand the use case, I've checked #1775 and #749 and I'm still lost with how it should works.

What I suggest here is to close this PR, and redoing it for the upcoming v3.1.0. But could you add one or more toggle in the editor instead? This would be easier to understand for the users, setting the steps to -1 doesn't feel intuitive. What do you think?

[Huckies]

Hi Clooos,

I wish to add toggles too, but I'm not familiar with CSS or javascript things, actually it's my first time writing in these languages.

The purpose is quite simple, the original slider can only match curtains physically installed on the left side and moving towards right when closing. If anyone's curtain is installed on the right side it's kind of counterintuitive. And if the curtain is two pieces of clothes closing to the center, even more.

So I'm offering a way to 'reverse' the slider: by setting it's start point to the right side, it can match the substance in real world, and one can set two symmetric sliders just like I do.

Would you please add some toggle buttons decently in v3.1.0? I'm really clumsy at this while it helps a lot if the UI is more intuitive for users to understand the slider could be reversed.

Hi! I've added this feature and more layout options for the sliders (in a new panel in the editor). I really think this will be much more user friendly. This will be available in the next v3.1.0 beta 😄
