Custom pad extension with extension icon after title

I'm trying to create a mat accordion with a mat expanding panel inside a for loop. The problem is, I need to make some customizations, like adding a checkbox in front of each extension, and the extension icon should be placed after some specific text (in this case the book title). The alignment is confusing, from my understanding the expansion panel icon can be placed at the end or the beginning. I think pad extension is the right component to achieve the same goal. Need some guidance on how to implement pad extensions, or is there another approach I should consider?

Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
