ScrollPosition not set to top when navigating to other pages

The web page is designed using a master-slave approach. The master has tabs (left pane) that, when clicked, display the corresponding pages in the slaves (right pane). For example. master has three two tabs "Schema and Templates" where the schema is displayed by default. The user can navigate between these two pages (loaded by the slave page) using the tabs in the left pane (loaded by the master page).

File reorganization causing problems with selections, hyperlinks and import templates?

I'm using jQuery to import a common template file into certain parts of the page. Everything works perfect until I organize my file structure differently. Now, my SELECT dropdown doesn't work except for the title, and even though VSCode autopopulates half of the regular hyperlinks, I can't keep track of them so I know I've rewritten the new path correctly. Everything seems to be where it should be in the code, but random parts don't appear or can no longer be clicked. I feel like my months worth of work has become a mess and I don't know how to fix it! One of my biggest questions right now

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. 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
