    def paint(self, painter, option, index):
        super(InventoryDelegate, self).paint(painter, option, index)
        if not index.parent().isValid():
            painter.save()
            painter.setPen(QtGui.QPen(QtGui.QColor("white")))
            r = QtCore.QRect(option.rect)
            r.adjust(0, 1, 0, -1)
            painter.drawLine(r.topLeft(), r.topRight())
            painter.drawLine(r.bottomLeft(), r.bottomRight())
            painter.restore()

    def sizeHint(self, option, index):
        s = super(InventoryDelegate, self).sizeHint(option, index)
        s.setHeight(55)
        return s

class Inventory_Items(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(Inventory_Items, self).__init__(parent)

You have to iterate over the items that have the feature name and hide if necessary, if all the children are hidden the parent too.

def search_item(self):
    filter_text = self.le.text()
    is_valid_filter = filter_text == ""
    for i in range(self.inventory_widget.topLevelItemCount()):
        top_item = self.inventory_widget.topLevelItem(i)
        flag = (str(filter_text).lower() in str(top_item.text(1)).lower())  or is_valid_filter
        top_item.setHidden(not flag)
