By default, a maximum of 10 devices and 10 device groups is shown in the 
Input and 
Output categories of the palette (see also 
    
Adding a block). When you use the search boxes that are available for these categories, this default also applies to the maximum number of assets that are shown in the search result. When you click 
Load more, up to 10 more devices, device groups and/or assets are shown.
The same default value is used in the block parameter editor when you select a different device, device group or asset (see 
    
Editing the parameters of a block) and when you replace devices, device groups or assets (see 
    
Replacing devices, device groups and assets).
If you want to change this default value (to show either more or less items), you need to change the tenant options. That is, you need to send a 
POST /tenant/options request. For detailed information, see the information on tenants in the
