How to specify default value for block parameters¶
As you probably know, you can create a new block in a layout by drag and dropping it from the left sidebar to the layout. This means that there is no way to specify the starting values for the parameters in the block. Instead, the default values provided in the block definition are used.
This is not a problem per se, but it does mean that in cases when you do need different starting values than those provided by the block definition, you need to add a block and immediately edit it in the right sidebar to change the parameter values to more suitable ones. This only slows down layout creation process.
To overcome this, you can specify default values for any block parameter in the configuration. For example, if you want to change the default number of columns of a Grid block, you would use a configuration like this one:
block_types: grid: defaults: parameters: number_of_columns: 6
From now on, every time you add a Grid block to your layout, it will be created with 6 columns.
