I am trying to show/hide a table based on the input selection. Based on my first dropdown if the user selects a value wave2 it should show the table 2 under the 1st tab else it should hide. I tried to use the react input select value to if else condition for output which is not how react works in R. Could someone please check and let me know on where I am wrong .
