    @Aviral-0
    You are ignoring what I am writing. I told you how to do that, you have not acted on it.

    @JonB I have tried it bro... I tried removing !index.parent.isvalid()
    and placing some other functions.
    I am not fully understanding of what you are suggesting. can you tell me what to write there?

    Screenshot (227).png

    QVariant DomModel::data(const QModelIndex &index, int role) const
    {
        if (!index.isValid())
            return QVariant();
    
        DomItem *item = static_cast<DomItem*>(index.internalPointer());
        const QDomNode node = item->node();
    
       // if ( role == Qt::CheckStateRole && !index.parent().isValid())
        //if ( role == Qt::CheckStateRole && index.column() == 0 )
        if ( role == Qt::CheckStateRole && (index.column() == 0)  )
        {
            return static_cast< int >( item->isChecked() ? Qt::Checked : Qt::Unchecked );
    }
        if (role != Qt::DisplayRole)
            return QVariant();
    
        switch (index.column()) {
            case 0:
                return node.nodeName();
            case 1:
            {
                const QDomNamedNodeMap attributeMap = node.attributes();
                QStringList attributes;
                for (int i = 0; i < attributeMap.count(); ++i) {
                    QDomNode attribute = attributeMap.item(i);
                    attributes << attribute.nodeName() + "=\""
                                  + attribute.nodeValue() + '"';
                }
                return attributes.join(' ');
            }
            case 2:
                return node.nodeValue().split('\n').join(' ');
            default:
                break;
    
        }
    
        return item->data(index.column());
    }
    
    
    Qt::ItemFlags DomModel::flags(const QModelIndex &index) const
    {
        if (!index.isValid())
            return Qt::NoItemFlags;
    
        Qt::ItemFlags flags = Qt::ItemIsEnabled | Qt::ItemIsSelectable;
    
        if ( index.column() == 0 )
            flags |= Qt::ItemIsUserCheckable;
        return flags;
    }
    //! [6]

      I am not your "bro"! You need to replace the original && !index.parent().isValid() with the condition for QDomNode node not having any children.

        @JonB You don't know anything, just arrogant rude. I didn't find any solutions to my problem from you!

          What about "You need to replace the original && !index.parent().isValid() with the condition for QDomNode node not having any children." from @JonB - did you do that?

          Please state polite...

            Just wow! I have made over a dozen posts so far over a week trying to help you solve your issues. Told you at each stage what to do, and at least a couple of times what to do now. Why don't you have a look back up? Thanks for nothing, bro.
