I am using Eonasdan bootstrap datetimepicker in paramquery grid. From starting I have faced one problem, If I open datetimepicker, the calendar is hiding inside the grid. When I given the css condition

```css
.dropdown-menu {
position: fixed;
}
```

it is working. The calendar is visible clearly but it is not open in a correct place. After given "position:fixed", If I click picker icon the calendar is open in right-top of the grid or right-bottom of the grid. It is not open in an exact place. How can I resolve this?
