### Begin of the insertionAcceptance criteria

#### Basic - Copied from <mention class="mention" data-id="31992" data-type="work_package" data-text="#31992">#31992</mention> 

* For work packages without start/finish dates but _with_ duration, the width of a &quot;strip&quot; representing such a work package on hover on a GANTT view has a width that is relative to its total duration (on drag over GANTT).
* &quot;Relative&quot; because width depends on the zoom level of the GANTT chart.
* On click, end date is calculated based on the the start date selected.
* If the duration is very long one (finish date is outside of current view), the user will first have to click to commit, and then zoom out or scroll to view the finish date.
* If the user modifies a work package via the drag handles on the left/right edges of the strips the in Gantt chart, both the start/finish date as well as the duration are altered in lockstep, based on which side is dragged.
* If non-working are included for that work package (via the date-picker), they will need to be taken into account in the GANTT too (for example, the work package should span the weekend if the weekend is included).
