Hide the symbol expand/collapse. Hierarchies in web templates

Hello, i´m using the a web template to show the results of one query that uses a hierarchy. We have just selected in the query the option to show all the nodes and display all levels of the hierachy. What we need is to hide the symbol of the node because of, in our case, it´s not necessary. The hierrachy is completely expanded so we want to hide the symbol expand/collapse of the hierarchy.

We are using a web template and the web item "Table" to show the results in the browser.

It´s possible to hide this symbol using some java code ? or maybe some option of the web item ?

Thanks in advance for your suggestions.
