Create Selectbox using nested options source

Sometimes is necessary to modify the Select box.
Here is an example how to use the same Options source
under different conditions.

The example uses the page variables "fullbox" and "shortbox".
The select options are defined somwhere (can be in an other page). They can be hidden in the >>comment<< block .

fullbox

yes

shortbox

yes

Show full selectbox (options A1,A2,...C1)

 
(:if equal {$:fullbox} yes:)
(:include {$Group}.{$Name}#Lev2#Lev2end:)
(:input select name="mybox" C1 C1:)
(:ifend:)

Show shorten selectbox (options A1,A2,...B2)

(:if equal {$:shortbox} yes:)
(:include {$Group}.{$Name}#Lev2#Lev2end:)
(:ifend:)

>>comment<<
[[#Lev2]]
(:include {$Group}.{$Name}#Lev3#Lev3end:)
(:input select name="mybox" B1 B1:)
(:input select name="mybox" B2 B2:)
[[#Lev2end]]

[[#Lev3]](:input select name="A" 1 A1:)
(:input select name="mybox" 2 A2:)
[[#Lev3end]]
