Today, we accomplished another task in LibreHatti. A two-level drop-down has to be implemented in Librehatti whenever a Lab Report has to be generated. Earlier, this was actualized using one drop-down each on one page. It was like lab was selected on one page and when submitted, the user was taken to another page that asked for selection of material corresponding to the lab selected.
So AJAX again came into action and we settled this, implementing dependent drop-downs here too. Nothing was related to admin in this case.
It was quite easy. Then scrutinized kernel of LCv3.
