Add listDefinition/Columns only to specific folder

Question

I would like add Columns that show data of the component but only within a specific folder. I can already show extra columns with the requested data, but now they show up everywhere (it is becoming a mess).

The reason is that I will need to add columns in multiple folders with different data. I would not want all the columns continually visible as it will result in one big mess.

Dynamically hiding the columns with JavaScript also just seems to messy and I assume that there should be a way to do this with just the customEditor.config file.

In response to Alvin Reyes comment on this question:

We have at this moment 3 content types, and expanding, with each their own needed data. This data is specific to that content type.

I also though about just making generic columms which would be filled in according to what is needed. The found disadvantages were:

1. the number of extra data for each content type is not the same, this would still result in empty columns (max empty would be 4).
2. It would result in not being able to add the needed translation to the right data.

Therefore, being able to hide the columns through their definition within the editor configuration file would result in allot less client sided JavaScript processing.

Answer 1

Found the solution:

Instead of extending an existing list I added a listdefinition:

<ext:listdefinitions>
    <view name="DashboardView">
         <control id="FilteredItemsList">
             <listdefinition idmatch="^tcm:\d+\-26-2$" url="xml with your list definition in defined" />
         </control>
    </view>
</ext:listdefinitions>

Here ^tcm:\d+-26-2 points to the folder 26 within all publications and therefore only apply this list definition at that specific folder.
