Dashboards: Variable values are truncated

[russorat]

the issue here is that the important part of this value is the very end, that is truncated.

• When the drop down is opened, we should expand the list horizontally to show the full value of the the variable.

@alexpaxton is this a clockface change or can we do this entirely in influxdb?

Should be doable entirely in InfluxDB

• Fixed width menu
• Dropdown should expand to size of items contained
