Hello J P,

You could do this with either JavaScript or jQuery, although it will involve the use of custom code and manual editing of the HTML which WebSite X5 produces.

The following articles should point you in the right direction if you decide to use JavaScript...

However, WebSite X5 includes the jQuery library as standard, so it may be even easier (and neater?) to make use of the jQuery hide() and show() methods:

If you're not familiar with scripting then I'd strongly recommend an alternative method of hiding the text, such as linking to it via a Showbox, which is something which can be done quickly and easily using WebSite X5's built-in tools.
