I deleted CSS code you point out and now sandwich menu is showing but, it is showing double, how I can remove extra one? Also, how I can show sandwich menu icon to show on the left side at the beginning and also do the same on the right side to the end for search icon?
Thanks David, I added CSS code you recommend and it seems it removed double one, now how I can place sandwich menu icon to the left and place it to the left start and search icon to the right end?
