CFv4 Elements and HTML

A 'combo' box is a linked pair of a select drop-down and a text input set up so that the text box is only enabled (and required) if the 'Other' option is selected in the drop down; otherwise it is empty and disabled.

It's quite common on a form to have one part that repeats several times. If the number of repeats varies then it can be useful to have an 'Add one' button that will add an extra copy of this part of the form. An example might be for a booking form where one booking can be for several people and you want to enter all of their names. This FAQ shows you how to do this when the number of repeats is limited e.g. up to x people.

These three form elements: select drop-downs, checkbox groups and radio button groups all accept lists of options i.e. value+label pairs. This FAQ shows you several ways in which ChronoForms can create option lists. Most of the FAQ will look at select drop-downs but the same methods can be used with checkbox groups or radio button groups.

The most common example of this request is when you need to have both a billing address and a shipping address and you want to copy the address over to save the user filling out the same or similar details twice. This FAQ looks at some ways to do this with JavaScript.

ChronoForms makes it easy to create forms but it's not always obvious how to use them. This FAQ talks about four ways you can display them. 

In some browsers (but not all) if you have tool tips on your inputs then tabbing between inputs will also tab to the tooltip links. Here's a JavaScript snippet to prevent this: 

Simple forms with a few inputs are very easy in ChronoForms. But many forms have tens, sometimes hundreds of inputs and then it can become difficult to build in the Form Wizard Preview box. Here are some suggestions for making it easier to build large forms.

There are several different kinds of form input that you can use in HTML. Text inputs and text areas are the most commonly used. After that come select drop-downs, radio buttons and checkboxes? Each of these allows the user to select one or more options from a preset range. This FAQ looks at the differences between them.
