Selection-Dependent Inputs

Getting form usability right ...

"In a previous Communication Design column, “Refining Data Tables,” I alluded to the importance of Web forms in online commerce, communities, and creation. As arbitrators of checkout, registration, and data entry, forms are often the linchpins of successful Web applications.

But successful Web applications tend to grow—both in terms of capability and complexity. And this increasing complexity is often passed on to and absorbed by a Web application’s forms. In addition to needing more input fields, labels, and Help text, forms with a growing number of options may also require selection-dependent inputs.

Selection-dependent inputs are, in essence, a pretty simple concept: Once a user initially makes a selection from one or more options in a form, the user must provide additional input related to the selected option before submitting the form. Figure 1 illustrates this behavior by showing two steps from the eBay Create a Download Request form. After an eBay seller selects the Sold option in the Listings and records drop-down list, the form presents additional input fields for selecting a date range. Were the user to select a different option in the Listings and records list, completing the form would require a different set of additional options."    (Continued via UXmatters)    [Usability Resources]
