Why does the slider not expand inside the horizontal box?

[Cestarian]

I put a slider in a horizontal box, but it’ll only get about as wide horizontally as the width of the handle, how can I make it fill all available space in the box?

I’ve tried the various fill settings for the slider and the box and even removing that little text that’s also in the box so only the slider is in it but nothing seems to work.

The reason i’m doing it this way (horizontal box inside a vertical box) is because I want to display the value of the slider next to it, rather than above or below it.

you should be able to just set the slider to fill under this hierarchy

Oh I tried that but it didn’t work, but I figured it out from your screenshot, I needed to enable fill horizontally, although I’m pretty sure I had tried that before, i tried all combinations.

Anyhow now it works, thanks!
