Place an onclick on the textarea to call a function to grab the cursor position and save it to a global variable.
Use the code:
document.getElementById("IdTextarea").selectionStart;
Then create a function that takes the value of the selected select with onchange and selected index (or whatever you prefer) and enter the value in the previously collected position.
conteudo = document.getElementById("IdTextarea").value;
pt1 = conteudo.substring(0,pos);
pt2 = conteudo.substring(pos);
document.getElementById("IdTextarea").value = pt1 + selecionado + pt2;
where the variable pos is equal to the value of the cursor position you collected in the other function.
