How to build a collapsing menu for my order form?

If you are selling different categories of products or services, you can improve the structure of your online order form by using a collapsing menu.

How to build your collapsing order form menu? In a few easy steps. For example purposes, we will assume there are three categories of products or services, each with its own suboptions.

  • In the Form Editor, add six Checkbox fields to your order form: three containing a single option that designates the category name, and three listing the options available in each category.

  • Now it’s time to make the suboption sections scrollable. Use the following code: #rowsec2, #rowsec4, #rowsec6 {height:150px; overflow-y:auto; border:1px solid #ccc;} and replace the IDs with the ones referring to the suboption fields in your form. And you’re done with the CSS.
