Creating fixed FCE with fluidcontent - fluid

Question

Width this code i can define content:
<flux:flexform.section name="columns">
<flux:flexform.object name="column" label="column">
<flux:flexform.field.input name="demo" label="Demo field" />
</flux:flexform.object>
</flux:flexform.section>
<flux:flexform.grid>
<flux:flexform.grid.row>
<f:for each="{columns}" as="sectionObject" iteration="iteration">
<flux:flexform.grid.column>
<flux:flexform.content name="column{iteration.cycle}" label="Column {iteration.cycle}" />
</flux:flexform.grid.column>
</f:for>
</flux:flexform.grid.row>
</flux:flexform.grid>
This is flexible. I can Add new "Content Areas" through the section. But this is not what I want. I Want to define a very fixed two-column and a three-column FCE. My editor should not have to decide how many columns to use.
I am missing something like:
<flux:flexform.field.contentArea name="col1" label="Column 1" />
<flux:flexform.field.contentArea name="col2" label="Column 2" />
<flux:flexform.grid>
<flux:flexform.grid.row>
<flux:flexform.grid.column>
<flux:flexform.content name="col1" />
</flux:flexform.grid.column>
<flux:flexform.grid.column>
<flux:flexform.content name="col2" />
</flux:flexform.grid.column>
</flux:flexform.grid>
</flux:flexform.grid.row>
Thank you for your hint to the right direction.

You are very close to the solution with the code you already have. In this example I will use the new ViewHelper names - but you can get the same result using the old names as in your example. Which is which, should be easy to spot (note: you had a typo in your code example which I edited, rgid used instead of grid - such a typo would cause Flux to error out):
<flux:grid>
<flux:grid.row>
<flux:grid.column>
<flux:content name="col1" label="Nice name for column 1" />
</flux:grid.column>
<flux:grid.column>
<flux:content name="col2" label="Column 2" />
</flux:grid.column>
</flux:grid>
</flux:grid.row>
And remove the flux:form.section with object inside it - you don't need this when you make a statically defined grid.
Then to render this grid:
<flux:content.render area="col1" /> and so on.
