Re: Editing the Members widget. (I have ok XHTML & CSS knowledge)
Sure. So you can do two things:
- Use CSS to style the members widget to look like the recent active widget (just copy/update the existing CSS)
- Clone the recent active widget into your child theme’s functions.php file and change the call it make to be like the members widget
Changing the CSS is probably the easiest, just set anything you don’t want displayed to display:none and it will disappear.
Cloning is the cleanest and can be easily shared back to the community for other people trying to do the same thing.
