WordPress sometimes inserts extra line spaces (empty <p> tags). To remove the extra line space, try wrapping the content in <div> tags.

Using the <Enter> or <Return> key to add extra line spaces may not always work. The <br> tag also may not work because it only breaks up content that’s on the same line.

To add extra line spaces we need to use &nbsp; which stands for “non-breaking space.”

For example, to add a line space at the top of the [dropdown] content, use &nbsp;

These are some of the quirks in WordPress that users need to work around.
