To remove auto-generated columns in Webflow's tablet view and create a navigation bar with only 4 columns and 2 rows, you can follow these steps:
1. Start by designing your navigation bar in the Desktop view with the desired layout of 4 columns and 2 rows.
2. Switch to the Tablet view by selecting the Tablet icon in the top bar of the Webflow Designer.
3. In the tablet view, you'll notice that the columns you created in the Desktop view might have been automatically adjusted to fit the tablet screen size. To remove these auto-generated columns, you need to override the default settings.
4. Select the parent element of your navigation bar, which could be a div block or a navbar component. In the Navigator panel on the left, click on the parent element to access its settings.
5. In the Style tab on the right, scroll down to the Layout section. By default, you'll see the Display property set to "Grid". Change it to "Block" or "Flexbox" depending on your preferred layout approach. If you choose Flexbox, you can use flexbox properties like justify-content and align-items to position your navigation items.
6. Next, you need to set the width of your navigation bar to accommodate the 4 columns. You can do this by going to the Size section in the Style tab and manually inputting the width value. For example, if each column should be 25% of the container, set the width to 100% and the columns' width to 25%.
7. Now, select each individual navigation item within the navigation bar. Adjust the dimensions (width, height) and spacing between them to fit the 4-column, 2-row layout. You can use padding, margin, or flex properties to achieve the desired spacing and alignment.
8. You also need to ensure that the navigation items respond correctly to smaller screens. You can do this by using the Responsive menu component or applying media queries to hide or stack the navigation items when needed.
9. Finally, preview and test your website in the Tablet view to ensure that the navigation bar appears as intended. You can use the preview mode or publish your site to see how it looks on different devices.
Remember, Webflow provides a powerful design tool, so feel free to experiment with different layouts, styling options, and interactions to create a unique navigation bar that suits your needs.
