In order to get a widget from your listing to put into your site, go to your business listing, and click on "Widget" tab.
In order to personalize it, you can select the border color, the background color (you don't have to know HTML colors, you can click on our color selector and choose the color you want), the size of the widget (sometimes you have a narrow space, so you can select the height and width of the widget), you can also select the map zoom (whether if you want it closer or farther). and if you want some of the features disabled, such as Tags, Address or Map view.
When you select "Generate code", a code will be generated, and you can see the preview for your selections.
You can always change the options, and when you settle with the perfect option for your site, you can copy and paste the code generated into your site!
