Is there a CSS-style approach for UMG?

I am not an expert of UMG framework, but I know that is a very powerful tool.
I wonder if there are some particular settings to set the style for those objects who share the same appearance, like css for html.
For example, when I create a menù usually many buttons in a vertical box share the same style, but I have to repeat manually the same operation for all.
Is there a way to speed up this process?

For your button example, you can make a new blueprint that contains a button with the styling you want, then use that blueprint in place of your button. You can also make a new blueprint or c++ class that derives from UButton.

Whether it’s faster or not depends on what you’re trying to do. If it’s just a few buttons with the same styling, I would probably just do it by hand. If it’s a consistent part of your workflow though, it’s worth it to make the blueprints.

It really comes in handy when you want to do something weird, but still take advantage of the built-in class. For example, if you want to programmatically add blueprints with your custom styling.

yes, if you look in your options u have combo boxes at try this at any time and any aspect not just in the ui or with buttons but pre CTRL+D and you will be surprised that it does the opposite of delete!( you can also do this with entire sections like a row of 6 buttons 2 row of 2 and another of six,trow a button in ctlr+D (now select both) repeate, move 1 down and select the 3 ctrl+D select 6 in the row, ctrl+D move to bottom add button in(id be faster) set next to the solo button and select both n duplicate again. thats more complicated than it needed but that work flow state of mind with speed the entitre prodject up at least cutting 1/3 of time spent out!
