The plugin allows you to select records through tables based on one-to-one or one-to-many relationships specified within a QGIS project.
After the installation a tool bar with three buttons will appear:
- the first icon: 'Allows selections by relationship' activates/deactivates the plugin;
- the second icon Select Relationship, a drop-down menu, allows you to activate the project reports; by default no relation is selected, so the plugin does not work;
- the third icon 'settings' has three options:
- Zoom to Feature to of Parent Layer;
- Select Feature(s) of Child From Parent Layer;
- Active Parent Layer;
