QUESTION
I have prepare 2 tree view in separate iframe using jstree. The right tree view should control the left tree view. When user click one one the list in right tree view, the respective item folder will open and selected on left tree view. I can make it happen using div in single page. I control the left tree view using instance of left tree view in right jstree div var instance = $('#left').jstree(true);.
ANSWER
Answered 2021-Jun-16 at 03:07I had used document.getElementById('1').contentWindow.jQuery('#left').jstree(true); to get instance from iframe with id='1'. In order to listen to right iframe(with id='2') if any menu has been clicked, I used document.getElementById('2').contentWindow.jQuery('#right').on("changed.jstree",function(e,data){}). I get the instance of left iframe within this function. By using this instance, I has deselect previous selection, select current selection, and open children of selected menu.

QUESTION
I'm trying for a long time to get my labels on the left side on my input fields. I'm banging my head against the wall. I use a font-awesome icon in the label.
I tried a lot of searches on Google and Stack Overflow and tried stuff like inline-block which I see should work but it didn't work for me. My code so far. I guess it's an easy fix for all the great people that are here.
...ANSWER
Answered 2021-Apr-13 at 19:11The easiest method, in my opinion, is to turn .wrapperSnippet into a CSS Grid layout.
Grid is supported by all modern browsers but IE supports an older version of the spec.
We can define the grid with two columns: one of width auto, and the other with 1fr. auto means that it will take up as much space as needed to fit the element, then the 1fr will fill the remaining space.

Answered 2021-Jun-15 at 10:46It's because that shape is made with linear gradient as background, so you just need to adjust gradient percentages:
From
background: linear-gradient(25deg, yellow 50%, transparent 50%);
to
background: linear-gradient(25deg, yellow 20%, transparent 20%);
