Use Form Control to Add Value to Attribute

[dreifsnider]

Hello!

I'm trying to implement a form control to let authors easily control the values of the @outputclass attribute. I'd like for them to be able to add a variety of attribute values in a variety of combinations. For example, I'd like for them to be able to set the @outputclass for an image directly in Author Mode to various combinations of float-left, box-shadow, and thumbnail.

I've tried using both oxy_checkbox and oxy_combobox, but both of these directly overwrite the entire @outputclass values with the selected value instead of simply adding the value.

Essentially, I'm wondering if there's a way to simply append a value to the existing attribute values instead of entirely overwriting the attribute values.

Thanks!
Daniel

Hello,

If you know all the possible values that the outputclass attribute will have, writing them in the values part should be enough:

Code: Select all

oxy_combobox(edit @outputclass, values "box-shadow, float-left, other-value1, other-value2")

If this solution does not work for you, you'll need to implement an AuthorOperation [1] that changes the attribute of the currently selected node [2].
Best,
Gabriel

Thank you for your reply Gabriel!

Unfortunately, I don't think the oxy_combobox will work, because it looks like a user can't select more than one option at a time, for example, they wouldn't be able to select both float-left and box-shadow; it's either one or the other. I supposed I could add every combination of values as a separate, unique value, but this seems unmanageable especially given that the list of allowed values can potentially grow.

I will explore the other form controls to see they would work instead, specifically, checkbox and popup.

I will also look into create a custom Author Operation, but my Java skills might not be enough to do this successfully.

Thanks again!
