In the attached Sample Workbook, you will find 4 tabs. A "Summary Sheet" tab and 3 Data Tabs. On the Summary Sheet in Column 'A', there are check boxes next to each Bid Package. Each Bid Package will have it's own tab in the original document, but in the sample workbook attached, there are only 3 Bid Package Tabs provided. At the top of Column 'P', you will find a toggle button labeled "Show All / Hide Inactive Bid Packages". I want this toggle button to be able to hide all rows on the summary sheet and the corresponding Bid Package Data Tab for any rows where the check box is blank or inactive. And then, once the toggle button is pressed again, it should unhide all rows and tabs making everything visible. The desire here is for me to be able to select which Bid Packages are Active, meaning which data tabs need to be visible in the workbook and which rows need to be visible on the Summary Sheet, by simply checking the corresponding box in Column A of the Summary Sheet, and then pressing the toggle button at the top of Column P. I want to eliminate the need for manually hiding rows on the summary sheet and manually hiding tabs in the worksheet. What is the proper macro code that should be used for the toggle button to properly accomplish this? Please keep in mind that I am a novice here, and will need good step by step instructions. Thank you!
