Answered Dashboard Widget Sizes

Am I missing something when creating Dashboard widgets?

I create a simple HTML widget with a size of double but it is still only one row high, I change it to full and it is the same height as double.

According to the documentation: "Size - Widgets come in 3 sizes - half, full, and double. A half-sized widget takes up half of one row. A full takes up one whole row. A double takes up 2 rows."

I think it's referring to containers in the layout. One column container, a full row container, or two row containers.

If your widget doesn't fill up two row containers in CSS it will appear as a single row for responsiveness.

Correct me if I'm wrong, but that's been my understanding. I'd like further clarification if I am wrong, also.

That's correct. The height of a widget is determined solely by how much content it displays. The settings only control the width. If you want it taller, you could throw in some
tags. I think you could also use CSS to set wide margins and/or padding.

Thanks for your replies. I am putting in an iframe with an 800 pixel height using CSS. It starts scrolling vertically after approximately 400 pixels are shown no matter if using full or double.

You should be able to override that in your own CSS file. If the widget uses PHP, the CSS can be loaded by the widget with $modx->regClientCss(). That will load it after all the Manager CSS.
