Find Tilda's own widgets in the category Form and button.
Change the appearance of your widget in a block's settings. Choose background colours, icon colour and add animation.
The widget's position on a computer screen can be configured only for desktop PCs (resolution from 980px and higher). For mobile devices with screen resolutions in the 0 to 980px range, the widget will be set in a fixed position in the bottom part of the screen.
If you'd like to collect information from your widget, such as telephone numbers, email addresses or messages, all you need to do is link your site to one of 12 data capture services integrated with Tilda.
When a customer is looking at your website on their mobile phone and taps a callback widget button, it makes a call. On desktops, a tap will open a form where customers can leave their phone number for you to call them back.
Add block BF901 to your page (Blocks library > Form and button > Widget for ordering call back)
When a customer clicks the button on a desktop PC, a callback form opens.
Tick your selected data capture service in the Content menu if you'd like customer information information to be sent there.
