Just create it as a standard block using the number of columns needed. Create the text and hyperlinks as required.
Add another standard bloc above the menu bloc in which to create the logo and hamburger link (no need to use the built in navigation bar options) Make this a two column bloc and add your logo to the left bloc Inside an image bric and a hamburger icon in the right of the bloc (also via an image bric) Align and size the elements as required. With the hamburger icon selected, create an interaction of “Toggle Visibility” and target the menu bloc id. Select the menu bloc and remove its visibility. When you preview, clicking the hamburger icon will cause the menu to appear. Clicking again will cause the menu to disappear.
You can enhance the design a little more by adding an X icon next to the hamburger icon. This will have the same toggle visibility interaction, only it should now target the id’s of the hamburger icon, the menu bloc and the X icon. Its initial visibility will be set so that it isn’t visible. On the hamburger interaction, add the X icon and hamburger icon id to the target list in the interactions section. In preview, clicking the hamburger Icon will cause the menu to appear AND the X icon to replace the hamburger Icon. When the X icon is clicked, the menu will disappear and the hamburger icon will reappear.
Instead of using images, you could use buttons. You would then create a class for each button to add the hamburger and X image to the button background.
