Such element becomes a node, when you insert/add/move it 
at/to the right place in the DOM-tree.

The htmltext-file that is used to build up your page 
is already parsed/executed and converted to a DOM-tree,
so forget about HTML-strings for now.

Now you are manipulating that DOM-tree [*1],
and each <option> is a new element/node, 
and each "text" in that element is a new text-node.

So if you re-use an earlier created[!] node,
you lose the function it had. 

So if you have 3 <option>-nodes and want a fourth and fiveth one,
you have to create TWO new ADDITIONAL nodes.

==============

[*1] if you use .innerHTML instead of DOM-commmands to insert something,
you in effect do a NEW parsing of that string, but that hampers your 
learning process as it does now, so better AVOID .innerHTML for now.
