How add a custom layout and switch different layout for the content?

[gaojianzhuang]

Sometimes, we need to create different layouts for the different content.
For now, the theme only has one "Layout.liquid" file, if I create a new layout file "Layout-LeftBar.liquid", how to use it?

I don't think we have built-in alternates for the Layout shape, but you don't need those for such a scenario anyway. Check out the different Content alternates: https://docs.orchardcore.net/en/latest/reference/modules/Templates/#content-templates

Thanks Piedone. I have tried to define a different content template, but it only supports the content level. Sometimes, we need the site-level template. How to define it? Thanks.

You could add your own alternate, which is easy enough with a bit of coding, see e.g. WidgetAliasShapeTableProvider.

Why the Layout-LeftBar.liquid is not a zone?

Regarding your question, I have never seen such an alternate. Please elaborate of what you are trying to do

For example, we need two layouts in one site. We need to switch between different layouts for different content.
My question is how to define different layouts with orchard core. Could you please introduce the solution?
Thanks so much. :)

What if you switch between the layouts after checking the content item by slug?

I think it should be the content type level not content item level. We can config the mapping for the content types with the layouts.
