How can I customize grails select tag

Question

I want to customize grails select tag

I tried this code

 <g:select name="totalHour" from="${1..20}" value="${holdingVacationInstance}"/> 

this code select options look like this

1, 2, 3, ... , 20

then, how can i make like this

0.5, 1.0, 1.5, ... , 20.0

Answer 1

Using the 'from' attribute you'll either have to give the select options as a list or as a Groovy Range.

IMO the latter is a more solid way to go:

Groovy range with a 0.5 step size

Answer 2

You can use like this

<g:select name="totalHour" from="${(0.5..20).step(1)}" value="${holdingVacationInstance}"/>

Then it will give output like [0.5, 1.5, 2.5, 3.5, ...] as per my concern you can't use non integer step. See here http://grails.asia/groovy-range-examples
