Hi its nothing with hbox layout and fieldset. Its is due to selectField.these lines are the border of selectField. If you want to remove it you need something like this
{
xtype: 'selectfield',
placeHolder: 'selectfield',
autoSelect: false,
border: 0,
},
this will make it disappear these line
i hope you get it ;)
here is a simple fiddle
And In case if you want to have borders follow this code
{
xtype: 'selectfield',
border: 3,
style: 'border-color: blue; border-style: solid;',
flex: 1,
placeHolder: 'selectfield',
autoSelect: false,
},
{
xtype: 'textfield',
border: 3,
style: 'border-color: blue; border-style: solid;',
flex: 1,
placeHolder: 'textfield'
}
