redirect = function(sectionname){

document.location.assign('about/' + sectionname + '/');
};

if block menu mean html menu made of other html elements divs, ordered / unordered lists response below applies, other that, please explain in detail mean block menu

select object contains reference html "select" tag, options in line var opsarray= select.options; code provided not work block menus.

you have have create function looks totally different.

let's menu:

<ul id="list">  <li id="about" onclick="redirect(this.id)">about</li>  <li id="news" onclick="redirect(this.id)">news</li> </ul> 

your javascript code have be:

redirect = function(sectionname){   document.location.assign('projects/' + sectionname + '/');     }; 

this 1 way it, there many ways this. understood question correctly.
