Accordion migration 2.6 to 4.4

I tried to upgrade from 2.6 to 4.5 but accordion doesn’t act the same:
2.6: DHTMLx 2.6 Accordeon Example - JSFiddle - Code Playground
4.4: DHTMLx 4.4 Accordeon Example - JSFiddle - Code Playground

I want the “blablabla” to be under the accordion and should still be under when we open a tab.

Any idea?

Please, try to update your css to the following to see the result:

html, body {
	width: 100%;
	height: 100%;
	margin: 0px;
	padding: 0px;
	overflow: hidden;
}
div#accObj {
	position: relative;
	width: 360px;
	height: 50%;
	box-shadow: 0 1px 3px rgba(0, 0, 0, 0.05), 0 1px 3px rgba(0, 0, 0, 0.09);
}

Thanks for the reply but it still doesn’t work:

I managed to make it work by tweaking the css:
