<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

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
