I want to have tabs, but since they need to be dynamic I am making use of local tasks. In the class extending DeriverBase I have written the following function:
public function getDerivativeDefinitions($base_plugin_definition) { $this->derivatives = array(); foreach ($this->moduleFormatManager->getDefinitions() as $key => $definition) { $this->derivatives[$key]['title'] = $definition['title']; $this->derivatives[$key]['route_parameters'] = array('module_format' => $key); $this->derivatives[$key]['route_name'] = 'module.format_configure_' . $key; if($key == 'xyz') { $key = 'newkey'; $this->derivatives[$key]['title'] = 'newkey'; $this->derivatives[$key]['route_name'] = 'module.newkey'; $this->derivatives[$key]['parent_id'] = "module.format_configure:xyz"; } } foreach ($this->derivatives as &$entry) { $entry += $base_plugin_definition; } return $this->derivatives; } In the above code, a tab for each key is being generated: my problem is in the if condition. In the if condition I am trying to generate a sub tab for a particular type of tab by declaring parent_id. But the code doesn't work for me.
What changes should I introduce in order to make it work? I used this link to learn about local tasks.
My module.links.tasks.yml file looks like this:
module.format_configure: title: 'Configuration' base_route: module.configure tab_root_id: module.configure deriver: 'path to deriver' All the mentioned routes have been declared in *.routing.yml file.
