Show modal in same position (height) as trigger of modal

[ellinge]

Fixes #72

Had to do a bit of a workaround since the table / modal is within an iframe so not easily fixed by only css.

Either way the modal is now positioned based on the offset height of the button which triggered it.

Not sure what to to with the build failing, tests seems to pass but I think your sonar-configuration is off.

Seems to have to do with the build being processed on my fork where the secret is missing:

The build fails for the reason you wrote. Please ignore it.
Regarding the changes, the fix should be possible without JS and just with CSS. Also, it would be good to update Bootstrap to the release version (now it uses Beta) before applying the fix - it might fix the issue.
I will take a look at it.
If none of it will help, then this PR will be accepted.

I don’t think it wont be doable with css only because the iframe viewport. It’s if bootstrap has some js to automatically apply it.

Basically this still applies (a quick google):

You are right. Bootstrap already sets it in the center, but the issue is that it is in an iframe.
