Grid - Elements - Add Row By Row

Flow
1

In the API, I do not see how to add individual rows to the elements grid.
I only see where I add items - a whole collection all at once.

Can I add row by row, column by column?

Hi Gunnar,
In case you want to modify the items array of element dynamically, you can use the
Polymer’s array mutation methods
. For example: grid.push(‘items’, {name: ‘foo’});
