I am attempting to make the sidebar in WordPress be made of a single unordered list. I am about 99% of the way there, but to get to that last 1% I am going to have to change the way that Widgets generate.
To be more specific, in default-widgets.php, the class called WP_Widget_Recent_Comments, function widget, there is code that generated a <ul> tag. I would like to remove that code and just return the <li> tags.
Now I do not want to have to do this every time WordPress needs to be upgraded.
Can someone tell me what the best practices would be to do something like this? I am very interested in maintaining a dynamic sidebar, but I do not want to do this at the cost of upgradeability.
You should not change the core files instead create your own widget using widgets api, here are some links for you
WordPress Widgets Api, another useful article about a step by step tutorial and a plugin here with comprehensive control about their appearance Get Recent Comments, hope it helps.
