How can I design a form with predefined parameters to choose from?

Question

Forms with Predefined Parameters

Answer 1

You can add default values to input via the 'value' attribute. What you are asking for (namely 'parameters to chose from') seems to be the select tag. Check your favourite search engine for select / option tags.

For anything fancier you will need to build your 'parameter-list' and control and design it via css / js, i fear.

What exactly are you trying to accomplish?

Answer 2

What exactly is your idea of the predefined parameters? I don't seem to understand what you're asking for : )
