How to add thumbnails in a choice list
Question
How to add thumbnails in a choice list, as we have in the bootstrap component to choose a predefined grid
Answer
Let's imagine such a definition:
[jnt:test] > jnt:content, jmix:basicContent
- testProp (string, choicelist[resourceBundle,moduleImage='png']) = 'val1' autocreated < 'val1','val2','val3'
This will declare a "test" component with a testProp property. This property uses the choicelist
with 2 initializers, resourceBundle
and moduleImage
.
resourceBundle
The resourceBundle
initializer will allow you to translate the values using the module properties file
jnt_test=My test component
jnt_test.testProp=My property
jnt_test.testProp.val1=Value 1
jnt_test.testProp.val2=Value 2
jnt_test.testProp.val3=Value 3
moduleImage
The moduleImage
initializer will tell the engine to load thumbnails for each value, based on the value name, meaning that you will have to create an img folder in your module src/main/resources/img
and then put one png image per value
src/main/resources/img/val1.png
src/main/resources/img/val2.png
src/main/resources/img/val3.png
